The main rings of Saturn were observed with the Planetary Camera of the WFPC2 instrument on the Hubble Space Telescope (HST) from September 1996 to December 2000 as the ring opening angle to Earth and Sun increased from 4 • to 24 • , with a spread of phase angles between 0.3 • and 6 • at each openin
